I can not display uf in the following situation:
$.post("<?php echo site_url('Welcome/viacep'); ?>",
{cep: cep},
function(dados){
alert(dados.uf);
},
'json'
);
But when I change the alert to alert(dados) , JSON appears complete.
What am I doing wrong?
You may have to do parse of json:
$.post("<?php echo site_url('Welcome/viacep'); ?>", {cep: cep},
function(response){
var dados = JSON.parse(response);
alert(dados.uf);
}
, 'json' );
Try this:
$.getJSON("//viacep.com.br/ws/"+ cep +"/json/?callback=?", function(dados) {
if (!("erro" in dados)) {
//Atualiza os campos com os valores da consulta.
$("#logradouro").val(dados.logradouro);
$("#bairro").val(dados.bairro);
} //end if.
else {
//CEP pesquisado não foi encontrado.
//limpa_formulário_cep();
errosend("CEP não encontrado.");
}
});
You need to convert this JSON that was received as text to a Object . You can use JSON.parse , the same native JavaScript, following form:
let obj = JSON.parse(dados);
Handling you use obj instead of dados .
alert(obj.cep);
jQuery also has a function to deserialize JSON, $.parseJSON , but it is considered obsolete, so you can use pure JavaScript as in the example given above.
As of jQuery 3.0, $ .parseJSON is deprecated. To parse JSON strings use the native JSON.parse method instead. Font
